The Mopar unit is very easy to set up and on a street car runs just fine--DO check the gap--if it is too big your timing will seem to "jump around" when looking at it with your timing light--The neat part about the Mopar unit is that with a torx driver you can adjust the length of the slots and add more initial timing which really helps if you have any mods like cam, etc Many folks work like crazy to try and get the carb to idle when all it needs is more initial advance
Shorten the slots a little, check the gap, get any box except the orange one and you will be fine
